Seo

SEO stands for search engine optimization, which is a set of practices designed to improve the appearance and positioning of web pages in organic search results. Because organic search is the most prominent way for people to discover and access online content, a good SEO strategy is essential for improving the quality and quantity of traffic to your website. 

To understand the value of SEO, we must break our definition into three parts: 

-  Organic search results 

-  Quality of organic traffic 

-  Quantity of organic traffic 

The unpaid listings on a search engine results page (SERP) that the search engine has determined are most relevant to the user’s query. Ads (in this context, PPC or pay-per-click ads make up a significant portion of many SERPs. Organic search results are distinct from these ads in that they are positioned based on the search engine’s organic ranking algorithms rather than advertiser bids. You can’t pay for your page to rank higher in organic search results. 

How relevant the user and their search query are to the content that exists on your website. You can attract all the visitors in the world, but if they're coming to your site because Google tells them you're a resource for Apple computers when really you're a farmer selling apples, those visitors are likely to leave your site without completing any conversions. High-quality traffic includes only visitors who are genuinely interested in the products, information, or other resources your site offers. High-quality SEO capitalizes on the search engine’s effort to match a user’s search intent to the web pages listed in the SERP. 

the number of users who reach your site via organic search results. Users are far more likely to click on search results that appear near the top of the SERP, which is why it’s important to use your SEO strategy to rank relevant pages as highly as you can. The more high-quality visitors you attract to your site, the more likely you are to see an increase in valuable conversions. 

Search engines like Google and Bing use crawlers, sometimes also called bots or spiders, to gather information about all the content they can find on the internet. The crawler starts from a known web page and follows internal links to pages within that site as well as external links to pages on other sites. The content on those pages, plus the context of the links it followed, help the crawler understand what each page is about and how it’s semantically connected to all of the other pages within the search engine’s massive database, called an index.

When a user types or speaks a query into the search box, the search engine uses complex algorithms to pull out what it believes to be the most accurate and useful list of results for that query. 

These organic results can include web pages full of text, news articles, images, videos, local business listings, and other more niche types of content.

There are a lot of factors that go into the search engines’ algorithms, and those factors are evolving all the time to keep up with changing user behaviour and advances in machine learning.
